IMPROVEMENT IN WELL-TUBING.

Specification forming part of Letters Patent No. 208,619, dated October1, 1878 application filed July 3,

To all whom it may concern:

Be it known that I, NOAH K. LUDLOW, of the city of Mobile, in the countyof Mobile and State of Alabama, have invented a new and usefulImprovement in Driven Wells, which improvement is fully set forth in thefollowing specification and accompanying drawing, in which- Figure 1 isa side view. Fig. 2 1s a vertical section.

The object of my invention is to furnish a well-point which can bedriven into the earth with little or no friction to the sides of thewell-tube above it, and to enable the tube to be withdrawn Withoutbreaking it.

My well-point consists of an inner strainertube, A, perforated withholes of a size in proportion to the diameter of the tube. Theperforated portion of the tube A is covered with an unbroken corrugatedbrass wire-gauze, B, attached thereto, and the lower end of the tube Ais inserted in a socket, E, of the cast-iron slip-point D. I make thepoint D considerably larger than the diameter of the Well-tube l itself,in order to relieve the latter as much as possible from friction indriving the Well. As the diameter of the point is greater than thediameter of the well-tube, it makes a larger opening in the earth forthe passage of the latter. The socket E strengthens the tube A, and incases where it is required to withdraw the well-tube from the earth, theslippoint D will become detached from the tube A and prevent it frombeing broken.

I prefer to make the tube A of brass or composition metal.

Having described my invention, I claim- The Well-point D, provided withsocket E, in combination with the perforated brass tube A and unbrokencorrugated brass wire-gauze, covering the perforated portion of tube A,said tube being detachably connected to the point, in the manner and forthe purpose described.
